Green encapsulation of LDH(Zn/Al)-5-Fu with carboxymethyl cellulose biopolymer; new nanovehicle for oral colorectal cancer treatment.

Numai utilizatorii înregistrați pot traduce articole

Due to the decrease of the drugs side effects in controlled drug delivery systems, today's many research has been focused on designing the new controlled drug delivery systems. The main aim of the present work was the improving of the layered double hydroxide (LDH) properties as a drug delivery

Relationship between tumor necrosis factor-α release and granulocyte and monocyte adsorption to cellulose acetate beads.

Numai utilizatorii înregistrați pot traduce articole

Tumor necrosis factor-α, (TNF)-α, a proinflammatory cytokine, is produced by activated granulocytes and monocytes (GMs) and implicated as a major factor in inflammatory bowel disease (IBD) pathogenesis. Reduction of TNF-α should improve IBD pathology. GM adsorptive apheresis (GMA) is an effective

Cellulose acetate beads induce release of interleukin-1 receptor antagonist, but not tumour necrosis factor-alpha or interleukin-1beta in human peripheral blood.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Dramatic improvements in clinical symptoms of rheumatoid arthritis and ulcerative colitis were observed after patients received granulocyte and monocyte adsorptive apheresis with a column containing cellulose acetate (CA) beads as adsorptive carriers. This study was to investigate the

Oxidized cellulose (Surgicel) granulomata mimicking tumour recurrence.

Numai utilizatorii înregistrați pot traduce articole

Oxidized cellulose (Surgicel) has been used as a haemostatic agent in neurosurgery for five decades. Complications have been few. Two cases are reported of granulomatous reaction to oxidised cellulose two months and twelve months after removal of intracranial meningiomas. Both appeared as contrast

A double-blind study on the effect of purified cellulose dietary fiber on 1,2-dimethylhydrazine-induced rat colonic neoplasia.

Numai utilizatorii înregistrați pot traduce articole

The incidence, distribution, size, and histopathology of grossly visible colonic tumors induced by parenteral administration of 1,2-dimethylhydrazine were examined in rats fed either a chemically defined fiber-free diet or a nutritionally and calorically equivalent diet containing a purified fiber

The proliferation of human tumor cell lines in the presence of different agars, agaroses, and methyl cellulose.

Numai utilizatorii înregistrați pot traduce articole

Human tumor cell lines, derived from cancers of the colon, ovary, and cervix, were grown in liquid tissue culture media and media made semisolid with agar (Bacto + deoxycholate lactose agar), agarose [LE, ME, Sea Plaque and Sea Prep (15/45)], and methyl cellulose. The effects of each agent on

Synthesis and characterization of iron oxide nanoparticles/carboxymethyl cellulose core-shell nanohybrids for killing cancer cells in vitro.

Numai utilizatorii înregistrați pot traduce articole

Novel core-shell superparamagnetic nanofluids composed of magnetic iron oxide (Fe₃O₄, MION) and cobalt-doped (Co_xFe_3-xO₄, Co-MION) nanoparticles functionalized with carboxymethyl cellulose (CMC) ligands were designed and produced via green

Multifunctional carboxymethyl cellulose-based magnetic nanovector as a theragnostic system for folate receptor targeted chemotherapy, imaging, and hyperthermia against cancer.

Numai utilizatorii înregistrați pot traduce articole

A multifunctional biocompatible nanovector based on magnetic nanoparticle and carboxymethyl cellulose (CMC) was developed. The nanoparticles have been characterized using TEM, SEM, DLS, FT-IR spectra, VSM, and TGA studies. We found that the synthesized carboxymethyl cellulose magnetic nanoparticles

Evaluation of the effects of hyaluronic acid-carboxymethyl cellulose barrier on ovarian tumor progression.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Hyaluronic acid is a prognostic factor in ovarian cancers. It is also a component of Hyaluronic Acid-Carboxymethyl Cellulose (HA-CMC) barrier, an anti-adhesion membrane widely used during abdominal surgeries in particular for ovarian carcinosis. 70% of patients who undergo ovarian surgery

Facile hydrothermal bio-synthesis of cellulose acetate templated CuS nanorods like fibres: antibacterial, cytotoxicity effects and DNA cleavage properties against A549 lung cancer cells.

Numai utilizatorii înregistrați pot traduce articole

In this research, the hydrothermal method was used for synthesising cellulose acetate (CA) templated nanorods like CuS fibres using vegetable extract (Brassica oleracea var. italica). These extracts act as a reducing agent in the presence of CA. Surprisingly, when the same reaction was

Self-assembled micelles prepared from bio-based hydroxypropyl methyl cellulose and polylactide amphiphilic block copolymers for anti-tumor drug release.

Numai utilizatorii înregistrați pot traduce articole

Fully bio-based amphiphilic diblock copolymers were synthesized from hydroxypropyl methyl cellulose (HPMC) and amino-terminated poly(l-lactide) (PLLA) or poly(l-lactide-co-dl-lactide) (PLA) by reductive amination. The resulting HPMC-PLLA and HPMC-PLA copolymers with various hydrophobic block lengths

A diet containing alpha-cellulose and fish oil reduces aberrant crypt foci formation and modulates other possible markers for colon cancer risk in azoxymethane-treated rats.

Numai utilizatorii înregistrați pot traduce articole

There is a need for better understanding of the roles of dietary fats and fibers in colon cancer risk. We examined the effect of different dietary fiber and fat sources on an azoxymethane (AOM)-induced colon cancer in rats. In a 2 x 3 factorial design, rats were fed a semipurified diet containing

Hollow microspheres based on - Folic acid modified - Hydroxypropyl Cellulose and synthetic multi-responsive bio-copolymer for targeted cancer therapy: controlled release of daunorubicin, in vitro and in vivo studies.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Conventional chemotherapy drugs such as anthracyclines show no specific activity. They destroy cancer cells but also and the healthy ones, and for that reason exhibit high toxicity. In order to alleviate the toxic effects of chemotherapeutic drugs, the administration dose is being

Overcoming multidrug resistance of breast cancer cells by the micellar doxorubicin nanoparticles of mPEG-PCL-graft-cellulose.

Numai utilizatorii înregistrați pot traduce articole

The amphiphilic block copolymer methoxy-poly(ethylene glycol)-poly(epsilon-caprolactone) (mPEG-PCL) was grafted to 2-hydroxyethyl cellulose (HEC) to produce nano-sized micellar nanoparticles. The nanoparticles were loaded with anti-tumor drug, doxorubicin (DOX) and the size of the DOX-loaded

Chemotherapy of Breast Cancer Cells Using Novel pH-Responsive Cellulose-Based Nanocomposites.

Numai utilizatorii înregistrați pot traduce articole

Purpose: The objective of the current study was to compare the anticancer efficacy of doxorubicin-loaded cellulose based magnetic (Fe₃O₄), zinc oxide (ZnO) nanoparticles on and free doxorubicin (DOX) on MCF-7 breast cancer cells. Methods: Novel pH-sensitive
